本発明は、ガスや石油を燃料とし全一次燃焼を行なう燃
焼機器において着火時の空気比制御をおこなう燃焼制御
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a combustion control device that controls the air ratio at the time of ignition in a combustion device that uses gas or oil as fuel and performs primary combustion.
従来の技術
この種の全−火燃焼機器においては、空気量を理論空気

に悪影響を与えるといわれるN O2、NOx等の窒素
酸化物の発生を極度に抑制することができるという利点
を有していた。Conventional Technology In this type of all-fire combustion equipment, the amount of air is set at an air ratio of 1.0 or more, which is greater than the theoretical air amount. It has the advantage of significantly lowering the flame temperature by reducing the combustion rate, which greatly reduces the generation of nitrogen oxides such as NO2 and NOx, which are said to have a negative impact on the human body. Ta.

よ、易いヶ態いあ。However, on the other hand, the higher the air ratio at the time of ignition, the lower the fuel concentration, which makes it difficult to ignite instantly, takes time to ignite, or even fails to ignite. Toxic emissions (i.e. carbon oxides, hydrocarbons, carbon dioxide, etc.) due to delays, etc.
Oh, it's so easy.

着火時の低空気比(空気比1.0以下)での燃焼時間を
抑え、急速に高空気比(空気比1,0以上)に移行する
燃焼制御になっていた。Ta. For this reason, a method has been considered in which the amount of combustion air is controlled to below the theoretical air amount of the fuel at the time of ignition, and the amount of air is increased after ignition to shift to steady combustion at a high air ratio.
Generally, combustion air is supplied by a blowing fan, so it is difficult to rapidly control the air ratio due to a response delay in rotation speed, etc., and a combustion state where the air ratio is below 1.0 will exist for a while due to this response delay. As a result, large amounts of harmful substances such as carbon monoxide and hydrocarbons were generated. For this reason, conventional combustion equipment of this type has been equipped with a switching valve in the combustion air supply path to quickly switch the air ratio. The combustion control was such that the air ratio was suppressed and rapidly shifted to a high air ratio (air ratio of 1.0 or more).

It was easy to cause the phenomenon of As a result, the generation of toxic emissions due to incomplete combustion increased significantly, and there was a risk of misfire occurring, which was extremely harmful to the human body.

酸化炭素等の有毒排出物は極度に低減される。1 is a burner; fuel is supplied from a fuel tank 2 to a fuel pump 3 through a multi-fuel nozzle 4 to a carburetor tube 5; The premixed gas is vaporized and mixed within the combustion chamber, and is supplied as a premixed gas to the burner 1 to form a combustion flame 8. Reference numeral 9 detects the ionic current in the combustion flame 8 with a flame rond, and detects the flame state. A controller 10 controls these combustions. This controller 10 includes an air amount transmitting section 11 that transmits a signal of the amount of combustion air to be supplied to the blower fan 6.
A signal is sent to the combustion amount transmitter 12 that sends a combustion amount signal to the fuel pump 3, and the air switching valve 14 that opens and closes the air port 1b in the air path 7 that releases a part of the combustion air to the outside. It has a switching transmitter 15 for transmitting data. At the time of ignition, multiple signals are transmitted from the air amount transmitter 11 to the combustion air, and the combustion air is supplied to the burner 1 through the fan drive circuit 16 by the air blower 7A 6. On the other hand, the fuel is supplied to the burner 1 by the fuel pump 3 after multiple signals are transmitted from the combustion amount transmitter 12 and passes through the pump drive circuit 17 . At this time, each signal is transmitted at a ratio of combustion air to fuel, ie, an air ratio slightly greater than 1.0. However, at this time, the air switching valve 14 receives the signal from the switching transmitter 15 and causes the switching valve drive circuit 18 to open the air port 13, so that the air ratio is less than 1.0. In other words, a smaller amount of air than the theoretical amount of air for fuel is being sent to the carburetor cylinder 5, and a premixture rich in fuel is supplied to the burner 1, so that it can be easily ignited. However, since combustion in this state is an air-deficient state, the fuel is not completely combusted, producing harmful carbon monoxide and hydrocarbons. Therefore, at this time, the ignition is detected by the flame detection section 19 using the ion current from the flame rod 9, and at the same time, a signal of this flame detection is sent to the switching transmission section 15, and the signal from the switching transmission section 15 is transmitted via the switching valve drive circuit 18. The air switching valve 14 is activated to instantly close the air port 13. As a result, during combustion immediately after ignition, an air amount slightly higher than the stoichiometric air amount of the fuel is suddenly supplied, and toxic emissions such as sea oxide carbon during complete combustion are extremely reduced.

後のCo発生状態を示す。At the same time, when the flame detection section 19 roughly detects ignition, the air amount transmitting section 11 receives this flame detection signal and gradually increases the air amount to set a constant air amount (slightly higher than the theoretical air amount of the fuel). Send a signal to the air blower 7 An 6 so that the air ratio is a high air ratio in the stable combustion region (this value differs slightly depending on the type of burner, but in general, the air ratio is about 1.5 for a full-fire combustion burner). As a result, a high air ratio is reached when the temperature near the flame opening of burner 1 has risen sufficiently, making it possible to transition from ignition to steady combustion with a stable flame (combustion occurs near the theoretical air amount). The combustion speed is the fastest, the flame temperature rises easily, and the atmosphere temperature rises easily.However, as the amount of air increases, the combustion speed decreases and the flame temperature becomes lower, and cooling by the air itself (The temperature near the burner nozzle is difficult to rise.) Therefore, no lift phenomenon is observed due to insufficient temperature rise at the burner nozzle, and as a result, the amount of carbon monoxide generated is significantly reduced, and during stable combustion. Safe combustion with extremely low nitrogen oxide production can be achieved. Note that FIGS. 3 and 4 show the state of Co generation after ignition in the case of combustion control using a conventional air path switching valve and in the case of combustion control according to this embodiment.
